Abstract: The paper presents the cache controller from following aspect: the address-mapping, the cache accessing flow, the replaced algorithm and the policy on write misses. The key issues in design, such as how to keep the consistency between the IU and cache and how to produce a burst memory accessing, are also analyzed in the paper. The cache controller has been embedded into Lilac system which verified by FPGA and manufactured using TSMC 0.25μmCMOS technology.
